Do not bend the terminal base more than terminals. twisting torque to the terminals. 45° when the product is mounted in a fixed position. Product terminals can be welded using direct welding and series welding methods. In either case, please use a suitable jig so that the device will not be subjected to the stress conditions listed above. Pull strength and detach strength of the terminal welds are per user requirements. However, if the welding is controlled by resistance, the measurement should be made as close as possible to the weld point by a “4-point clip method” using milliohm meter to ensure accuracy. Avoid putting stress on the device, as listed above, when a jig, fitting or additional welding process is used. Please reconfirm the resistance value whenever a new process is added. 6 Littelfuse.com ©2016 Littelfuse, Inc.

Battery Devices Installation Guidelines for The Strap Family • PPTC devices operate by thermal expansion of the conductive polymer. If devices are placed under pressure or installed in spaces that would prevent thermal expansion, they may not properly protect against damage caused by fault conditions. Designs must be selected in such a manner that adequate space is maintained over the life of the product. • Twisting, bending, or placing the PPTC device in tension will decrease the ability of the device to protect against damage caused by electrical faults. No residual force should remain on device after installation. Mechanical damage to the PPTC device may affect device performance and should be avoided. • Chemical contamination of PPTC devices should be avoided. Certain greases, solvents, hydraulic fluids, fuels, industrial cleaning agents, volatile components of adhesives, silicones, and electrolytes can have an adverse effect on device performance. • PPTC strap devices are intended to be resistance welded to battery cells or to pack interconnect straps, yet some precautions must be taken when doing so. In order for the PPTC device to exhibit its specified performance, weld placement should be a minimum of 2mm from the edge of the PPTC device, weld splatter must not touch the PPTC device, and welding conditions must not heat the PPTC device above its maximum operating temperature. • PPTC strap devices are not intended for applications where reflow onto flex circuits or rigid circuit boards is required. • The polyester tape on PPTC strap devices is intended for marking and identification purposes only, not for electrical insulation. • The coating on MXP devices is intended to prevent oxidization/aging of the devices. Damaging the coating or causing the coating to delaminate can have negative effects on device performance and should be avoided. • MXP devices have a small PPTC chip size and therefore have weaker peel strength between the polymer and Ni-foil of the chip. Excessive mechanical force to the device may cause delamination of Ni-foil from the polymer.

Solder Reflow • Recommended reflow methods: - IR - Hot air - Nitrogen • Recommended maximum paste thickness: 0.25mm (0.010in). • Devices can be cleaned using standard methods and aqueous solvents. • Experience has shown the optimum conditions for forming acceptable solder fillets occur when a reasonable amount of solder paste is placed underneath each device’s termination. As such, we request that customers comply with our recommended solder pad layouts. • Customer should validate that the solder paste amount and reflow recommendations meet its application. • We request that customer board layouts refrain from placing raised features (e.g., vias, nomenclature, traces, etc.) underneath PolySwitch devices. It is possible that raised features could negatively impact solderability performance of our devices.

Battery Devices Battery Application Summaries Protection for Lithium Cells and Lithium Battery Packs External shorts, runaway charging conditions or abusive charging can cause considerable damage to primary and secondary Lithium (Li) cells. PolySwitch disc and strap circuit protection devices can help protect rechargeable lithium batteries used in notebook computers and cellular phones, as well as other portable electronic applications. • PolySwitch strap devices Typical Rechargeable Lithium Battery Pack Circuit Diagram • PolySwitch disc devices + – PolySwitch Electronic Protection Module Strap Device Li Cell . . . Annular Disc PolySwitch Device Rechargeable Li battery pack Protection for Lithium-Ion/Lithium Polymer/Nickel-Cadmium/Nickel-Metal-Hydride Battery Packs The same conditions (external shorts, runaway charging, etc.) can cause both battery cells and battery pack surrounds to sustain damage. The most common applications for PolySwitch strap devices are for helping to protect Lithium-ion (Li-ion) and Lithium-Polymer (LiP) cell battery packs used in cell phones, digital cameras and laptop/notebook computers. They are also suitable for helping to protect nickel- cadmium (NiCd) and nickel-metal-hydride (NiMH) battery packs used in portable electronic applications. • PolySwitch strap devices NiMH/NiCd Battery Pack Single Cell Li-ion/Li-Polymer Circuit Protection Diagram Battery Pack Circuit Diagram PolySwitch Device PolySwitch Device + + Li-ion/ Control Li-Polymer IC n x 1.2V Thermistor Cell Thermistor Ident Ident – – Protection for Rechargeable Lithium Polymer Cells Tablets, ultra-thin notebook PCs and other small portable electronics that use high- capacity LiP and prismatic cells, require overtemperature protection to help prevent the cells from overheating. These applications’ thin form factors, high cell capacities and high battery discharge rates create a unique set of circuit protection requirements, which are low thermal cutoff temperatures (<90°C), high hold current ratings (>60A) and compact size. The MHP-TA series of MHP (Metal Hybrid PPTC) devices helps solve these design concerns by offering two levels of current carrying capacity (6A or 15A hold current at 25°C) as well as an ultra-thin package (L:5.8mm x W:3.85mm x H:1.15mm).
